Interactive evaluation of Riemann sums
rsums(f) interactively approximates the
integral of f(x) by Middle Riemann
sums for x from 0 to 1.
a graph of f(x) using 10 terms
(rectangles). You can adjust the number of terms taken in the Middle
Riemann sum by using the slider below the graph. The number of terms
available ranges from 2 to 128.
f can be a string
or a symbolic expression. The height of each rectangle is determined
by the value of the function in the middle of each interval.
the integral for x from
